1960 Map of Clearlake Oaks

About this map

Clear Lake dominates the southwestern corner of this survey, defining the shoreline where Clearlake Oaks and Glenhaven served as established communities at the start of the 1960s. The map highlights the area's geological and indigenous history, notably at Sulphur Bank Rancheria and the nearby Sulphur Bank Mine. Moving inland, the landscape rises into the ridges of the Mendocino National Forest, where isolated outposts like Bartlett Springs and Hough Springs indicate the region's historic draw for their mineral waters.
